The most versatile belay/rappel device from Black Diamond, the ATC-Guide is now even lighter thanks to windows machined through the body. They also enlarged the auto-block release hole to accept a small carabiner. Multiple friction modes provide the optimal amount of stopping power when lowering or rappelling, and the device's guide mode lets you belay one or two seconding climbers off an anchor.
